Is there any need to rant on pulseaudio when the OP wants to use Jack
for audio production? Its the stated goal of pulseaudio to support
'normal desktop use', which obviously doesn't include ICE1712 chipsets.
If you have such a card you should be using Jack anyway (would you buy
one of those just to listen to youtube videos?).

Hello Mark,
Thanks for the feedback and I agree with the bass line, I hear something
different in my head when I listen to this song. For the final
recordings I hope I can get him to play some parts a bit differently.
And we'll post more, we're recording the next song and that one already
has a way more elaborate bass line ;)
Best,
Jeremy

[LAU] thinkpad t61 noise

Hey,
My thinkpad t61 makes a high frequency sound, pipipipipippi, not very
loud. Funny thing, when I stick in the usb mouse, it's gone... I only
have this issue when on battery. Suggestions for solution?
Is it right that there is one fan in the T61, on the left of the
keyboard? Then a other noise source might be the hdd on the right.
It's not that my T61 is very noisy, it isn't very silent either. Maybe
I could change the hdd.
Best regards,
\r

Many Thinkpads (and other laptops as well) emit high-pitched noise
when the CPU periodically goes into power save mode. As far as I know
there is no real solution. You can change some kernel or BIOS settings
to (partially) disable power saving, but that might reduce your
battery life quite significantly.
I once had a similar problem which could also be "solved" by plugging
in USB devices. Turns out there was a bug in the USB kernel driver
which caused continuous CPU wake-ups, and thus prevented the CPU from
going into deep sleep modes. This stopped the noise, but also
increased power consumtion by a couple of watts...
Incidentally, another way to keep the CPU awake is to simply run JACK :)
This page has a lot more information and many potential workarounds:

Could be an IRQ conflict. What does 'cat /proc/interrupts' report ?
What does lsusb report ?
